The sacroiliac joint can be painful when the ligaments get too loose or tense too much. Sacroiliac joint pain can occur when the movement of the pelvis is not the same on both sides. Possible causes of sacroiliac pain include arthritis, traumatic injuries, pregnancy and postpartum, systemic inflammatory conditions, and infections. Other possible contributors are spinal scoliosis, leg length discrepancy, and previous fusion of the lumbar spine.
Sometimes, there's no clear cause for sacroiliac pain. It can be a dull or sharp pain. It starts in the sacroiliac joint, but can extend to the buttocks, thighs, groin, or upper back. You may experience sacroiliac joint pain as a sharp, throbbing pain that radiates from the hips and pelvis to the lower back and to the thighs.
Sometimes you may feel numbness or tingling, or as if your legs are about to bend. Pregnancy is another cause of pain related to the sacroiliac joint due to the laxity of the surrounding ligaments due to the production of the hormone progesterone. Pregnant people who suffer from this condition are more likely to develop arthritis in the sacrificial joints, a risk that increases with each pregnancy. If you get up from the chair and feel pain in your lower back, it could be that the sacroiliac joint is acting poorly.
Associated with aging, arthrosis can affect the sacroiliac joint, spine, and other joints in the body. The body releases hormones that cause joints to relax and move more, causing changes in the way joints move. Diagnosing pain related to sacroiliac joint dysfunction (SI) involves obtaining a detailed medical history and performing a complete physical exam. Your doctor may also inject a solution of natural ingredients, such as saline, and anesthetics into your joint.
The sacroiliac joint is designed to withstand heavy, compressive loads that allow us to walk, run, jump, crouch, etc. When the bones of the sacroiliac joint are misaligned or when the cartilage breaks and causes the bones to touch, it can be painful. Rather, sacroiliac joint pain is often related to an underlying problem, such as facet syndrome, degenerative disc disease, herniated discs, or segmental instability. While AD primarily affects the sacroiliac joints, it can also cause inflammation in other joints and, more rarely, in the organs and eyes.
Other less common causes include certain genetic diseases, such as ankylosing spondylitis, in which the sacroiliac joint fuses automatically. Physical therapy, low-impact exercises (such as yoga), and massages can help stabilize and strengthen sacroiliac joints and relieve pain. However, just because arthritis is detected on images doesn't mean you'll experience sacroiliac joint pain.
